File ibm304134-power7-1 of Package gcc43
2008-08-08 Peter Bergner <bergner@vnet.ibm.com> * doc/invoke.texi: Add cpu_type power7. * config.in (HAVE_AS_VSX): New. * config.gcc: Add cpu_type power7. * configure.ac (HAVE_AS_VSX): Check for assembler support of the VSX instructions. * configure: Regenerate. * config/rs6000/rs6000.c (rs6000_override_options): Alias power7 to power5. * config/rs6000/rs6000.h (ASM_CPU_POWER7_SPEC): Define. (ASM_CPU_SPEC): Pass %(asm_cpu_power7) for -mcpu=power7. (EXTRA_SPECS): Add asm_cpu_power7 spec string. 2008-07-16 David Edelsohn <edelsohn@gnu.org> * config/rs6000/rs6000.c (processor_target_table): Remove duplicate MASK_POWERPC64 for power4 in previous commit. 2008-07-16 David Edelsohn <edelsohn@gnu.org> * config/rs6000/rs6000.c (processor_target_table): Add MASK_PPC_GPOPT for power4, power5, power5+, power6, and power6x. 2008-02-26 Ben Elliston <bje@au.ibm.com> * config/rs6000/rs6000.h (ASM_CPU_POWER5_SPEC): Define. (ASM_CPU_POWER6_SPEC): Likewise. (ASM_CPU_SPEC): Pass %(asm_cpu_power5) for -mcpu=power5. Likewise, pass %(asm_cpu_power6) for -mcpu=power6. (EXTRA_SPECS): Add asm_cpu_power5, asm_cpu_power6 spec strings.
